Megacon KCC112E Electronics Control

KCC112E protects against phase-, earth- and winding faults within the protected area (the stator) of large AC generators. It detects even minute insulation punctures, flash-over carbon deposits and contamination. The unit measures highest up differential current from antiparallelled CTs in a Merz-Price configuration, by comparing current levels at the end of each phase winding.

 R1 is used for early warning. R2 or R3 (fail safe) is to be used for generator breaker trip, the "other" alarm relay can be used for local indication input to PMS, alarm system etc.

Alarm trip must be set sufficiently high to ensure that generator magnetisation current does not cause tripping. The alarm delay is to be set so that the initial inrush current have returned to normal level before the delay period elapses. The warning trip level and delay can be set as required to give early warning.

User settable trip levels and delays. Colour of LEDs indicates alarm status. LEDs flash during count-down. The meter and the triple-zone status LEDs at a glance gives the clear safety message:

• ALARM
• WARNING
• NORMAL
